Changjing · Schottky Diodes · TO-220-3L
SBD1045LCT from Changjing, in a TO-220-3L. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ANODE | passive | Anode terminal of the Schottky barrier rectifier in the TO-220-3L package, with the device rated at VRRM 45 V and IO 10 A average rectified current. |
| 2 | CATHODE | passive | Cathode terminal of the Schottky barrier rectifier in the TO-220-3L package, sharing the same 45 V VRRM and 10 A IO device ratings. |
| 3 | ANODE | passive | Second anode terminal of the Schottky barrier rectifier in the TO-220-3L package, sharing the same 45 V VRRM and 10 A IO device ratings. |
